Exactly 3 properties have an Occupancy Rate of at least 80% AND a Customer Satisfaction score of at least 8.5.

Among properties with an Average Daily Rate greater than $350, exactly 2 have a Customer Satisfaction score of at least 9.0.

No property in the Mountain region has an Occupancy Rate exceeding 80% OR an Average Daily Rate below $350.

All properties located in the Coastal region have an Occupancy Rate of at least 70% AND an Average Daily Rate of at least $350.

Exactly 4 properties satisfy at least one of the following criteria: Occupancy Rate greater than 85% OR Average Daily Rate greater than $400.

Cevabı ve açıklamayı göster

Cevap: Among properties with an Average Daily Rate greater than $350, exactly 2 have a Customer Satisfaction score of at least 9.0.; No property in the Mountain region has an Occupancy Rate exceeding 80% OR an Average Daily Rate below$ 350.; Exactly 4 properties satisfy at least one of the following criteria: Occupancy Rate greater than 85% OR Average Daily Rate greater than $400.

Cevap

The correct statements are those identifying 2 properties with ADR over

350 and satisfaction of at least 9.0, stating that no Mountain property exceeds 80% occupancy or has ADR below

350, and noting that exactly 4 properties satisfy either an occupancy over 85% or an ADR over $400.

The correct options properly execute multi-column boolean criteria (AND vs. OR). Specifically: filtering properties with ADR over

350 for satisfaction at or above 9.0 correctly isolates 2 properties; evaluating Mountain region properties confirms zero satisfy either occupancy over 80% or ADR under

350; and combining properties with occupancy over 85% or ADR over $400 correctly identifies a subset of 4 properties.

Adım Adım Çözüm

1

Evaluate the statement regarding Occupancy Rate

\geq 80\%

AND Customer Satisfaction

\geq 8.5

.

Properties meeting Occupancy

\geq 80\%

are Grand Azure (82%), Urban Vantage (88%), and Metro Elite (91%). Of these, Urban Vantage has a satisfaction of 8.4 (

< 8.5

). Only 2 properties meet both criteria, making this statement false.

Conjunctive filtering requires both conditions to hold simultaneously.

2

Evaluate the statement regarding properties with ADR

> \$350

having Customer Satisfaction

\geq 9.0

.

Properties with ADR

> \$350

are Alpine Haven (

\$410

), Solstice Resort (

\$450

), and Highland Lodge (

\$380

). Solstice Resort (9.3) and Highland Lodge (9.0) meet the satisfaction threshold (2 properties total), making this statement true.

First filter the subset by ADR threshold, then apply the satisfaction criterion.

3

Evaluate the statement regarding Mountain region properties having Occupancy

> 80\%

OR ADR

< \$350

.

Alpine Haven (75%,

\$410

) and Highland Lodge (79%,

\$380

) both fail both conditions. Therefore, 0 Mountain properties satisfy the OR condition, making the statement true.

Disjunctive filtering checks if at least one condition is met per property.

4

Evaluate the statement regarding Coastal properties having Occupancy

\geq 70\%

AND ADR

\geq \$350

.

Grand Azure has ADR

\$340 < \$350

, and Solstice Resort has Occupancy

68\% < 70\%

. Since neither satisfies both criteria, the statement is false.

A universal condition requires all items in the subset to satisfy the full compound logic.

5

Evaluate the statement regarding properties with Occupancy

> 85\%

OR ADR

> \$400

.

Occupancy

> 85\%

: Urban Vantage, Metro Elite. ADR

> \$400

: Alpine Haven, Solstice Resort. Combining these gives 4 unique properties, making the statement true.

An inclusive OR filter pools all elements that satisfy either criterion.

Cevap: True

Cevap

True

The statement is true. In the Business department, international students account for

\frac{150}{600} = 25\%

of total students. In the Engineering department, international students account for

\frac{160}{800} = 20\%

of total students. Since

25\% > 20\%

, the percentage is indeed greater in Business.

Adım Adım Çözüm

1

Calculate the percentage of international students in the Business department

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: False

Cevap

False

The statement is false because three Phase III candidates (Candidates B, C, and F) meet the specified compound criterion. Candidate B and Candidate C qualify because their Efficacy Scores exceed 80 (88 and 82, respectively). Candidate F qualifies because its Manufacturing Cost per Dose (

180) is less than

200. Because an 'OR' operator requires only one of the criteria to be met, all three candidates qualify, making the claim of 'exactly two' incorrect.

Adım Adım Çözüm

1

Filter the dataset for the primary condition: Trial Phase equal to Phase III.

Candidates B, C, and F are in Phase III.

The scope of the statement is restricted specifically to Phase III candidates.

2

Apply the compound logical condition (Efficacy Score > 80 OR Manufacturing Cost per Dose < $200) to each filtered candidate.

Candidate B: Efficacy 88 (>80) -> Satisfies condition.
Candidate C: Efficacy 82 (>80) -> Satisfies condition.
Candidate F: Cost

180 (<

200) -> Satisfies condition.

A disjunction (OR) requires at least one of the two sub-conditions to be true.

3

Count the total number of qualifying candidates and compare with the statement.

Total count is 3. The statement claims the count is exactly 2.

Since 3 does not equal 2, the statement is false.

Cevabı ve açıklamayı göster

Cevap: Beta Health; Epsilon Bio; Eta Dynamics

Cevap

The companies that qualify for shortlisting are Beta Health, Epsilon Bio, and Eta Dynamics.

The correct selections are Beta Health, Epsilon Bio, and Eta Dynamics because each satisfies at least two of the three stated conditions. Beta Health achieves Revenue Growth above 40% (45%) and Retention at or above 90% (92%). Epsilon Bio is Profitable and achieves Retention of at least 90% (94%). Eta Dynamics satisfies all three requirements.

Adım Adım Çözüm

1

Define the three evaluation criteria explicitly

Criterion 1: Revenue Growth

> 40\%

; Criterion 2: Profitable = Yes; Criterion 3: Employee Retention Rate

\geq 90\%

.

Clear definitions prevent boundary errors when filtering multi-column data.

2

Evaluate each company against all three criteria

Alpha Corp: C1 (No, 35%), C2 (Yes), C3 (No, 88%) -> Total: 1 criterion.
Beta Health: C1 (Yes, 45%), C2 (No), C3 (Yes, 92%) -> Total: 2 criteria.
Gamma Power: C1 (No, 28%), C2 (Yes), C3 (No, 85%) -> Total: 1 criterion.
Delta Pay: C1 (Yes, 50%), C2 (No), C3 (No, 78%) -> Total: 1 criterion.
Epsilon Bio: C1 (No, 40% is not > 40%), C2 (Yes), C3 (Yes, 94%) -> Total: 2 criteria.
Zeta Systems: C1 (Yes, 60%), C2 (No), C3 (No, 82%) -> Total: 1 criterion.
Eta Dynamics: C1 (Yes, 52%), C2 (Yes), C3 (Yes, 90%) -> Total: 3 criteria.

Systematic evaluation ensures no row or condition is miscounted.

3

Identify all companies meeting at least two conditions

Beta Health (2 criteria), Epsilon Bio (2 criteria), and Eta Dynamics (3 criteria) qualify.

Filtering for total criteria count

\geq 2

yields the correct subset.

Cevap

True. The median operational uptime for the filtered subset of tools (TL-01, TL-02, and TL-05) is 95.8%, which is greater than 95.0%.

The statement is correct (True) because applying the two compound criteria (Process Node

\le 5\text{ nm}

AND Defect Density

< 0.30\text{ defects/cm}^2

) selects tools TL-01, TL-02, and TL-05. The operational uptimes of these three tools are

95.8\%

Filter the rows based on the Process Node criterion.

Candidate tools meeting Process Node

\le 5\text{ nm}

: TL-01 (3 nm), TL-02 (5 nm), TL-03 (3 nm), and TL-05 (5 nm). Tools TL-04 (7 nm) and TL-06 (10 nm) are eliminated.

Only tools operating at 3 nm or 5 nm satisfy the condition of being 5 nm or smaller.

) to the candidate tools.

Qualifying subset: TL-01 (

0.24

), TL-02 (

0.18

), and TL-05 (

0.28

). TL-03 is excluded because

0.32 \ge 0.30

Cevap: 90

Cevap

The median operational efficiency of the solar power facilities in the North region is 90%.

Filtering the table for facilities in the North region yields six efficiency values: 82%, 85%, 88%, 92%, 94%, and 97%. Because the dataset contains an even count of six values, the median is the average of the two middle values (88% and 92%). Calculating

\frac{88 + 92}{2}

gives 90%.

"The median Q1 electricity consumption of branches in the North region is greater than the median Q1 electricity consumption of branches in the South region."

Is this statement True or False?

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: False

Cevap

The statement is False. The median Q1 electricity consumption for branches in the North region (

10,500\text{ kWh}

) is less than the median Q1 electricity consumption for branches in the South region (

14,500\text{ kWh}

).

The evaluation shows that the median Q1 value for the North region (

10,500\text{ kWh}

) is strictly less than the median Q1 value for the South region (

14,500\text{ kWh}

). Therefore, the assertion that North is greater than South evaluates to False.

Adım Adım Çözüm

1

Identify Q1 consumption figures for branches in the North region and calculate their median.

Branches in the North region are Alpha (

12,000\text{ kWh}

) and Gamma (

9,000\text{ kWh}

). The median is

\frac{12,000 + 9,000}{2} = 10,500\text{ kWh}

.

Filtering rows by the condition 'Region = North' isolates the correct values for statistical evaluation.

2

Identify Q1 consumption figures for branches in the South region and calculate their median.

Branches in the South region are Beta (

18,000\text{ kWh}

) and Zeta (

11,000\text{ kWh}

). The median is

\frac{18,000 + 11,000}{2} = 14,500\text{ kWh}

.

Filtering rows by the condition 'Region = South' isolates the comparison dataset.

3

Compare the two median values to evaluate the boolean statement.

Comparing

10,500\text{ kWh}

to

14,500\text{ kWh}

shows that

10,500 < 14,500

, making the statement false.

The statement claims North is greater than South, which contradicts the calculated result.

Statement I matches with True (West region average is 12.5 hours); Statement II matches with True (Gamma has highest shipments and lowest delivery rate); Statement III matches with False (3 out of 6 is exactly half, not more than half).

Each statement is evaluated against the data in the table: Statement I evaluates to True because the average for West warehouses (12.0 and 13.0) is 12.5 hours. Statement II evaluates to True because Gamma holds both the maximum shipment volume (15,200) and minimum delivery rate (91%). Statement III evaluates to False because exactly 3 out of 6 warehouses (50%) have delivery rates above 94%, which does not exceed half.

Adım Adım Çözüm

1

Evaluate Statement I by filtering by Region = West.

Beta (12.0 hrs) and Epsilon (13.0 hrs) are in the West. Average = (12.0 + 13.0) / 2 = 12.5 hours. 12.5 < 13.0 is True.

Calculate the mean value of processing time for the specified subset.

2

Evaluate Statement II by identifying the maximum shipment count and minimum delivery rate.

Maximum shipments = 15,200 (Gamma). Minimum delivery rate = 91% (Gamma). The condition holds True.

Determine if both extreme statistical properties apply to the same entity.

3

Evaluate Statement III by filtering for delivery rates > 94%.

Beta (96%), Delta (98%), and Epsilon (95%) qualify (3 warehouses). 3 out of 6 equals 50%, which is not > 50%. The statement is False.

Compare the count of matching rows against the threshold 'more than half' (strictly greater than 50%).

Cevap: Valley

Cevap

Valley is listed third from the top after performing the specified primary and secondary sorts.

Sorting the branches by Customer Satisfaction Score in descending order groups Harbor and South at the top with scores of 9.1. Ordering them by Q3 Revenue places Harbor first (

410 thousand) and South second (

380 thousand). The next highest satisfaction score is 8.8, held by Valley, placing Valley third from the top.

Adım Adım Çözüm

1

Identify the primary sort criterion and group branches by Customer Satisfaction Score in descending order.

Highest scores (9.1): Harbor, South. Next highest (8.8): Valley. Next highest (8.2): North, Metro. Lowest score (7.5): Summit.

The primary sort requires ordering by Customer Satisfaction Score from highest to lowest.

2

Apply the tie-breaker criterion (Q3 Revenue in descending order) to branches tied at a score of 9.1.

Harbor (

410 thousand) comes before South (

380 thousand). Rank 1: Harbor, Rank 2: South.

Ties in Customer Satisfaction Score must be broken by sorting Q3 Revenue in descending order.

3

Determine the branch in the 3rd position.

Valley has the next highest score of 8.8, placing it in Rank 3.

Since only two branches have a score of 9.1, the branch with the next highest score (8.8) occupies the 3rd row.

Cevap: True

Cevap

True. Exactly 3 out of the 5 divisions (Alpha, Gamma, and Delta) have a Revenue per employee greater than $250,000, which satisfies the condition of being more than half.

The correct evaluation is True because calculating the ratio of Revenue to Employees for each of the five divisions shows that Alpha (

266,667), Gamma (

320,000), and Delta (

300,000) all have a Revenue per employee above

250,000. Three out of five divisions represents 60% of the divisions, which is more than half.

Adım Adım Çözüm

1

Understand the condition and metric required

Need to calculate Revenue per employee (Revenue in dollars divided by number of employees) for each division and check if it is strictly greater than $250,000.

The statement specifies 'strictly exceeds $250,000' and applies to 'more than half' (at least 3 out of 5) of the divisions.

2

Compute Revenue per employee for each division

Alpha:

120M / 450 =

266,667; Beta:

200M / 800 =

250,000; Gamma:

80M / 250 =

320,000; Delta:

150M / 500 =

300,000; Epsilon:

300M / 1,200 =

250,000.

Performing explicit division allows precise comparison against the threshold value of $250,000.

3

Evaluate the threshold condition across all divisions

Divisions exceeding

250,000: Alpha, Gamma, Delta (Total = 3 divisions). Divisions equal to

250,000: Beta, Epsilon (Total = 2 divisions).

Values exactly equal to $250,000 do not satisfy 'strictly exceeds'.

4

Determine overall Boolean truth value

3 out of 5 divisions is 60%, which is more than half (50%). Thus, the statement evaluates to True.

Comparing the count of meeting divisions (3) against half of the dataset size (2.5).
